Having trouble understanding what this is asking and how to begin this step

"Inside the body of the loop, we're going to use the multiplier to get the multiple of 6. For example, if the multiplier is 1, then the multiple is 1 times 6, which is equal to 6.

Once you have a value, append it to the results array. This way once the for loop has iterated over the entire range, the array will contain the first 10 multiples of 6."

If someone could just help explain what this is asking and how to begin and why thats what you need to do, I would greatly appreciate it. Im having a hard time understanding where to begin.

Thank you!

loops.swift 
// Enter your code below
var results: [Int] = []

for multiplier in 1...10 {
    print("\(multiplier) times 6 is equal to \(multiplier * 6)")
}

Your for in loop is set up correctly. What the challenge wants you to do now is take the results of the for loop and append them to the array "results". So the body of your for loop will be appending the results of multiplier * 6

you are on the right track

How do I go about doing that?

Edit: I figured it out! Had to add

results.append(multiplier * 6)

Seems pretty obvious now, I must've been blanking.
